Search for $X (1870)$ via the decay $J / ψ \to ω K^{+} K^{-} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +649

Using a sample of $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ events collected by the BESIII detector at the BEPCII collider, we search for the decay $X (1870) \to K^{+} K^{-} η$ via the $J/ψ\to ωK…

Observation of structures in the processes $e^{+} e^{-} \to ω χ_{c 1}$ and $ω χ_{c 2}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +619

We present measurements of the Born cross sections for the processes $e^{+} e^{-} \to ω χ_{c 1}$ and $ω χ_{c 2}$ at center-of-mass energies $s$ from 4.308 to 4.951 GeV. The mea…
